JAMES H. BOWLING, OF RUSSELLVILLE, KENTUCKY.

CHURN.

Application filed August 4, 1915.

To all whom it may concern Be it known that I, Janus H. BOWLING, a citizen of the United States, residing at Russellville, in the county of Logan and State of Kentucky, have invented certain new and useful Improvements in Churns, of which the following is a specification, reference being had to the accompanying drawings.

This invention is an improvement on the churn shown in U. S. Patent #656,010, dated August 14, 1900, granted to C. IV. Bowling and has to do especially with the dasher, and the means for holding the dasher shaft.

In the accompanying drawings forming a 1 part of this specification, and in which like numerals of reference indicate similar parts in the several views:

Figure 1 shows a vertical elevation with parts broken away of a churn embodying my invention.

Fig. 2 shows a detached detail of the dasher disconnected.

Fig. 3 shows the dasher as disconnected.

Fig. 4: shows a detail of the dasher shaft as used in my invention.

Fig. 5 is a bottom view of the dasher.

In the patent to C. W. Bowling, #656,010, the dasher is made of two sections which are held to the spindle at the upper end by means of a split band which is drawn to gether by means of a set screw so that the upper end of the dasher is clamped to the spindle, the lower end of the two part dasher being held together by means of a collar, but being unsupported. This construction is found to be defective in that the dasher will waver, not having any guiding means at its lower end. This defect I have remedied.

In my present invention I provide a churn including a means for speedily getting butter out of cream, the construction being such that air is introduced into the cream during the churning operation.

In carrying out the aim of my invention I employ a base 1 which has the lateral extension 2 forming a support for the standard as used in my invention. This base 1 is provided with the circumscribing flange arranged to hold the can or receptacle A in place.

The standard as shown comprises a securing base 3 from which extends the standard 4. which in cross-section is T-shaped, this standard being secured to the base extension 2 by means of the bolts a.

Intermediate of its ends this standard 4 Specification of Letters Patent.

has a main bearing within which is held a stud 6, at one end supporting the driving gear 7 and at the opposite end having the head 8 secured to it, this head forming a part of the crank 9, to which is secured the handle 10, this construction being clearly shown in Fig. 1.

Located above the main bearing 5 is an upper bearing 11, within which is held the stub shaft 12 having a pinion 13 meshing with the gear 7 and a bevel gear 14. As shown this shaft 12 at its outer end is also supported by means of the bearing arm or hanger 15 depending from the upper end Z) of the standard 4, this upper end Z) termi nating in the end bearing 17.

Arranged to be held by the flange 0 of the base 1 is the can or receptacle A having the handle 2 and the lid 3, this lid 3 having a central opening 03 as shown. This opening is located immediately below the end hearing 17. The can A has a boss 19 having a securing flange 20 secured to its bottom.

Removably held within this boss at its lower end and within the bearing 17 at its upper end is the dasher shaft 21. This shaft at its upper end is provided with a bevel pinion 22 within the hub of which is secured a set screw 23 by means of which this bevel pinion is secured to the shaft, as shown in Fig. 1. This bevel pinion 22 is arranged to coa ct with the bevel gear 14.

Detachably secured to the shaft 21 is the separable dasher as used in my invention. This dasher as disclosed comprises two similar members, each embracing a half tubular portion marked 23 and 24; respectively, the member 23 having the collar 25 carrying the set screw 26 and at its lower end being provided with a plate 27 from which extends the agitating flange or rib 28. The half tubular member 23 near its upper end is provided with the intake opening 41, and near its lower end with the eXit or escape opening u, this opening u being located at a point below the head forming plate 27. This member 23 further at its lower end ends in the disk 30 having a central opening.

The counterpart member 24 is provided with an upper circular apertured plate 31 and a lower apertured disk 32, this plate 31 being arranged to lie upon the collar 25, while the lower disk 32 is arranged to lie upon the disk 30 upon the opposite member 23. The member 24 is also provided with an upper air intake opening 12 and a lower air escape opening to. This half tubular member 24: has the plate 25, which when the two members 23 and 2 1 are united is held in alinement with the member 27, as shown in Fig. 2. Extending from this plate 25 is the agitating flangeor rib 35,.

The tubular member 241: is provided with an unthreaded opening arranged to receive the set screw 26.

In securing the dasher in position the two members 23 and 24 are placed in juxtaposition so that these two members 23 and 24 form a complete tube. The shaft 21 is then inserted into the openings within the cir' cular members 25 and 31 and continued through the apertures within the members 32 and 30. The set screw 26 is then inserted through the member 24: and screwed .into the member 25 in which operation the screw 26 engages the shaft 21 to securely hold the dasher to the shaft in the manner shown in Fig. 2.

The intake openings 1) at all times should be at a point above the level of the cream within the receptacle.

On manually rotating the gear wheel 7 a rotary motion is imparted to the stub shaft 12 and in turn to the dasher shaft 21, resulting in the tubular .dasher being rapidly rotated. The rapid rotation of the dasher head and the connected agitating flanges throws the cream outward from under the bottom of the dasher, resulting in a partial vacuum being produced. As a result of this vacuum air is drawn down the hollow dasher through the opening 1) and set free at the bottom of the dasher. The released air nat urally rises up through the cream, resulting in the cream being aerated while being agis tated. This operation results in butter being speedily churned out of cream.

As shown the agitating ribs are located in parallel spaced relation upon opposite sides, however, of the hollow members 23 and 24:, from the lower end of which they tangentially extend, as disclosed in Fig. 5.

A churn constructed according to my invention is simple and inexpensive and both durable and eflicient in operation. The dasher can be readily cleaned and be removed or replaced with ease, accuracy and despatch.

Having thus described my said invention what I claim as new and desire to secure by Letters Patent is:

In a churn of the class described, the combination with arevolubly supporteddasher shaft, of a tubular dasher including two similar half tubular members each member having at its upper end an apertured circular collar and at the lower end a circular end forming apertured disk said shaft being held within the apertures of said disks and collars, one upper collar being held below the opposite collar while the lower disk of the other member is held above the oppositedisk whereby the ends of said members are made to-overlap, a set screw passing through one of said members and into the collar of the opposite member for locking said members to said shaft, each of said tubular members having an outstanding plate at its lower end from which extends an agitating rib, a vent opening being located below each plate and a bearing to hold said shaft at its lower end. v

In testimony whereof I affix my signature, in the presence of two witnesses.
